Embodiment Construction

[0018]Embodiments of the disclosure are now described in detail with reference to the accompanying drawings.

[0019]FIG. 1 through FIG. 3 illustrate a surface treating method for a metal housing, and FIG. 4 illustrates the formed metal housing. The metal housing 10 of the present disclosure can be widely used in automotive, electronics, telecommunications and other fields, especially if the product housings require metallic texture and high surface hardness, such as computer cases, cars, mobile phone housing, and so on.

[0020]As shown in FIG. 1 and FIG. 2, a workpiece 12 is provided, and a pretreatment is performed on a surface formed by a metal material of the workpiece 12. The metal material provides the metallic texture. In this embodiment, the whole workpiece 12 is made of metal, such as stainless steel, copper, iron, titanium, aluminum, magnesium or any alloy thereof. For example, the whole workpiece 12 is made of stainless steel in this embodiment, but not limited thereto.

Abstract

A surface treating method of a metal housing includes the following steps. First, a workpiece is provided. The workpiece includes a surface formed by a metal material. Thereafter, the workpiece is pre-treated to clean the surface of the metal material. Next, a titanium diffusion treating is performed on the workpiece to form a titanium-containing diffusion layer on the surface of the metal material.

Description

BACKGROUND[0001]1. Technical Field[0002]The present disclosure relates to a housing and a surface treating method, and particularly, to a metal housing and a surface treating method of the housing.[0003]2. Description of Related Art[0004]The development of electronic products and portable electronic devices such as mobile phones, music players, and personal digital assistants have allowed people to express themselves through the use of technology. The appearance of these portable electronics devices can become a selling point. A metal layer is usually formed on the surface of the portable electronic device, or the portable electronic device is assembled with a metal housing, to give a metallic texture to these devices.[0005]A coating layer is usually coated on the outer surface of the metal to protect the metal from corrosion, scratches, abrasion and oxidation. Although the outer coating layer can provide some protection for the electronic devices, the outer coating layer may corrod...
